Just got the latest PC Gamer with quite a few good looking previews. Call of Duty looks like the next really, really nice WWII game. Not only do you get to play the US/British role, but you get a chance at the Russian soldier in Stalingrad. If you're at all interested in WWII, I suggest reading War of the Rat, which Enemy at the Gate was loosley based on. Great book about the battle of Stalingrad.
Another one that caught my eye is Joint Operations. Using the Black Hawk Down engine. Looks really sweet for multiplayer.
